`S_(1) :` Silver iodide is fairly soluble in hypo solution.
`S_(2) :` Heavy metal chloride like `AgCl,HgCl_(2)` etc. also respond to Chromyl chloride test.
`S_(3) :` Bromine reacts with `KI` liberating violet vapours of iodine.
`S_(4) :` Diphenylamine reagent test is also given by nitrites chlorates, bromates, iodates, etc. in addition to `NO_(3)^(-)`

Consider the following statements : S_(1) : A metal chloride on heating with an aqueous solution of K_(2)Cr_(2)O_(7) and concentral H_(2)SO_(4) produces deep red vapours. S_(2) : Lead nitrate dissolved in water responds to brown ring test. S_(3) : Deep red solution of ferric acetate on boiling with water turns to brownishred solution. S_(4) : NaNO_(2) solution acidified with acetic acid produces blue colour with iodide solution and starch paste of these.

Consider the following statement: S_(1) : Cu^(2+) ions are reduced to Cu^(+) by potassium iodide and potassium cyanide both, when taken in excess S_(2) : H_(2)S will precipitate the sulphide of all the metals from the solutions of chlorides of Cu,Zn and Cd if the solution is aqueous. S_(3) :The presence of magnesium is confirmed in qualitative analysis by the formation of a white crystal S_(4) :Calomel on reaction with potassium iodide gives red precipitate. and arrange in the order of true/false.
